n. A mass complaint about one or more AP Chemistry worksheets assigned for homework. Such a complaint usually involves several students, and generally takes place directly in front of the AP Chemistry classroom in a "pow-wow" setting before class starts.

v. To complain, whine, or otherwise deny the validation of said AP Chemistry worksheets, either alone or with a group of people.

n. AP Chem student A: "Man, those reaction prediction worksheets were so difficult last night! I only solved two of the problems!"
AP Chem student B: "Don't worry; I had a really hard time doing those worksheets also, and I'm sure everyone else did, so we'll probably have a Kitch-Bitch tomorrow morning."

v. "Oh my God. These stupid equilibrium problems are impossible. I'm definitely going to Kitch-Bitch when this worksheet needs to be turned in!"
